Programmable electronic DC Loads for battery, solar cell, and power supply testing introduced by SIGLENT
By Mil & Aero staff
SOLON, Ohio – SIGLENT Technologies America Inc. in Solon, Ohio, is introducing the SDL1000X and SDL1000X-E series of programmable electronic DC loads for battery, solar cell, and power supply testing.
The SDL1020X/X-E models offer an input range of 150 volts at 30 amps with 200 Watts total power dissipation, while the SDL1030X/X-E's have an input range of 150 volts at 30 amps to 300 Watts. The X type provide a measurement resolution of 0.1 millivolt at 0.1 milliamps, whereas the economical X-E type offers 1 millivolt at 1 milliamps.
A four-wire sense compensation mode can remove any potential error due to a voltage drop in the connection wires. These DC loads for power testing testing support common modes of operation: CC, CV, CR, and CP.
One of the most important features of this new e-load series is its high-speed response performance. In dynamic test mode, the highest frequency of periodical switching between two user-defined levels (Level A and Level B) can achieve 25 kHz. Users can set up the adjustable slew rate.

All models come standard with a 3.5-inch TFT-LCD display and user interface. Operators can use the Program function (maximum 50 groups) and List function (maximum 100 steps) to create complex discharge profiles for battery charging circuitry design.
The SDL1000X/X-E series has an LED-test mode (CR-LED) for LED driver testing. This mode can emulate LED characteristics like single continuity. The instruments have a voltage threshold function, trend chart function, and voltage Rise/Fall speed test.
For maintaining security and reliability, the SDL1000X/X-E series provides over-current (OCP), over-voltage (OVP), over-power (OPP), over-temperature protection (OTP), as well as reverse voltage protection to prevent incorrect wiring connections to the device-under-test.
